• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) OR (su sach)) van nang xa hoi. hieu ((ve cac) or (vien cac)) xuc va thanh vi cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) van nang xa hoi. hieu ((ve cac) OR (vien cac)) xuc va thanh vi cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (su sach)) van nang xa hoi. hieu ((ve cac) or (vien cac)) xuc va thanh vi cua tu".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (su sach)) van nang xa hoi. hieu ((ve cac) or (vien cac)) xuc va thanh vi cua tu*.
